Java Floating Point Problem

Problem:
Java Floating Point Problem,
there is a problem with the binary representation of certain floating point numbers which could mess up your calculations.

Occurence:
While making a Android application which could add and subtract numbers, where I was using float variables.


Solution:
Using BigDecimal with the String constructor solved my problem, other solutions provided by other sources on the internet didn't match my requirements.


Note:

1. Pay attention that you use the String constructor 
2. BigDecimal is slower in calculations that float types
